Pressure Plates Now Have Collision?

I have this race track that uses ice as the road and boats as the vehicle. I have created traps (basically item boxes in Mario Kart) in the game that are activated by pressure plates as well as plates being used to restrict water. But since the new Nether Update on the Switch came out, boats can't get on top of pressure plates because of its new, increased height. Item drops can't activate pressure plates either for the same reason. Note that this all worked before the recent update.
